Description
Ultracold Neutrons (UCN) provide a unique tool for fundamental neutron research with long observation times.
The τSPECT experiment, which is currently being commissioned at the pulsed UCN source of the TRIGA Mainz research reactor, aims to utilize this fact in order to precisely measure the free neutron lifetime. In order to reduce systematic errors with respect to storage experiments using material bottles, τSPECT implements 3D magnetic storage of spin polarized UCN and will be able to measure both the decaying and the surviving UCN.
The current state of the τSPECT experiment and results from the first tests with neutrons will be presented.
